Patent number: 11497444Abstract: Provided is a biological information measuring instrument which can be easily and reliably worn on an appropriate position of an arm by a user. The biological information measuring instrument includes: a belt portion that is worn on a user's arm in a circumferential direction of the arm and disposed with a sensor for detecting a displacement of an arm muscle; and a case portion that is attached to a predetermined portion of the belt portion and houses a circuit component that processes a signal of the displacement detected by the sensor. The case portion has a shape of protruding from the belt portion in a longitudinal direction of the arm when the belt portion is worn on the arm, and amounts D1 and D2 of protrusions protruding in the longitudinal direction are different between one protrusion and the other protrusion.Type: GrantFiled: June 27, 2018Date of Patent: November 15, 2022Assignee: H2L Inc.Inventors: Emi Tamaki, Kenichiro Iwasaki
